There are various types of hydraulic oil pumps, including gear pumps, vane pumps, piston pumps, screw pumps, etc.
[0003] Compare the publicly disclosed patent No. CN 216589086 U for a high-pressure resistant hydraulic oil pump, which includes a hydraulic oil pump housing. A end cover is installed at the front end of the hydraulic oil pump housing. An oil inlet is arranged on one side of the hydraulic oil pump housing, and an oil outlet is arranged on the other side of the hydraulic oil pump housing. A driving shaft is rotatably connected to the lower end inside the hydraulic oil pump housing. A driving gear is fixedly sleeved on the driving shaft. One end of the driving shaft extends to the outside of the end cover and splines are arranged on the outer wall. A driven shaft is rotatably connected to the upper end inside the hydraulic oil pump housing. A driven gear is fixedly sleeved on the driven shaft. The driven gear is meshed with the driving gear. A heat-conducting inner sleeve plate is installed on the inner wall of the hydraulic oil pump housing. A plurality of groups of heat dissipation fins are equidistantly installed on the outer wall of the hydraulic oil pump housing. One end of the heat dissipation fin penetrates through the hydraulic oil pump housing and is fixedly connected to the heat-conducting inner sleeve plate. One end of the driven gear extends to the outside of the hydraulic oil pump housing and is connected with an auxiliary heat dissipation component. An installation seat is arranged at the bottom of the hydraulic oil pump housing, and a shock-absorbing base is arranged at the bottom of the installation seat. By setting the heat-conducting inner sleeve plate, the heat of the hydraulic oil flowing in the hydraulic oil pump housing is absorbed and conducted to the heat dissipation fins.

The heat dissipation fan is driven by the driven shaft to rotate, and the air outlet direction of the heat dissipation fan faces the hydraulic oil pump housing. Through the flowing air, the heat dissipated by the heat dissipation fins can be quickly taken away to further improve the heat dissipation.
